Method for removing oil from mill scale and

Iron oxide scale is continually formed on the surface of the hot steel. This scale is repeatedly stripped away by the stresses of rolling. The scale falls, together with the emulsified oil, into collection pits beneath the rolling mill, whence the oil emulsion is recycled via sumps and filters. The scale accumulates and is periodically removed.
